A new battery replacement can also repair iPhones that are running sluggish and randomly turning off.

A standard battery is designed to retain up to 80% of its original capacity at 500 complete charge cycles (about 1 year) when operating under normal conditions.

A good way to check your iPhone Battery Health is by going to: Setting > Battery > Battery Health.

If your battery is charging slower and discharging quicker than before - this could mean you have a charging IC (integrated chip) fault, but we would always recommend a battery replacement in the first instance.

When it comes to mobile phone batteries, no risk should be taken, these are lithium-ion cells that can expand and bulge out. Should the battery expand it can apply pressure onto the screen unit, causing additional damage. This expansion is caused by the build up of gases and are in rare cases highly flammable if released.
